Automatic rotation tray used between production field processes

The utility model discloses an automatic rotation tray used between production field processes. The automatic rotation tray comprises a rack, a rotation supporting board and a tray, wherein an upper bottom plate of the rack is inclined; a core shaft, a thrust ball bearing, a rotation sleeve and a radial bearing are vertically welded on the upper bottom plate; a positioning sleeve is welded at the center part of the lower surface of the rotation supporting board; rollers are arranged at the outer sides under the rotation supporting board; the rotation sleeve of the rack is installed inside the positioning sleeve of the rotation supporting board; a positioning sleeve is welded in the middle of the bottom board of the tray and is used for placing a positioning shaft welded at the center position above the rotation supporting board. With the adoption of the automatic rotation tray, the tray automatically rotates around the positioning shaft under the effect of own weight after an operator takes all products beside in production, so that the tray at the side with feeds automatically rotates downwards to approach the operator. Therefore, the operator does not need to push the tray with great effort, the labor and the time can be saved, and the production efficiency is improved.
